       Hardware- vs. Software-RAID. Which one?Reasons for using RAID include increasing fault tolerance through redundancy or improving data throughput.https://www.tuxedocomputers.com/en/Hardware-vs-Software-RAID-Which-one-to-choose.tuxedo#tuxedo #linux #instructions

       @tuxedocomputers I'd like to emphasize one big benefit and a massive drawback with hardware raid ...Pro: Many hardware RAID controllers can have a large read/write cache which is battery powered which can keep unwritten data alive for many days if there is long lasting power loss.  All data is automatically written to the disks as soon as the power is restored.  This also allows for a pretty good I/O performanceCons: In many cases, if the RAID controller breaks, you might not be able to easily recover data from the disks if you do not get the same hardware.  Different boards from the same vendor is usually safer, but need to check with the vendor.  If you try a RAID controller from a different vendor, you may destroy your data.Software RAID does not have the benefit of hardware cache and battery powered backup.  But that can be handled with a UPS on the computer with scripts which shuts down the machine before the UPS battery is empty.  Not as elegant, but does the job.However, mdraid (and possibly btrfs based RAID) is hardware independent.  As long as the right disks and partitions are added to RAID device, it'll work out - even when upgrading kernels.

       @tuxedocomputersSoftware. Please don't use Hardware-RAIDs anymore, even for HDDs.And PLEASE don't use Hardware-RAID on SSDs, especially NVMe.

       @tuxedocomputers often forgotten thing about software raid is that efi partition can not be software raided. One is left to sort efi partition redundancy by them selves.
